It should be noted that the ETC - electronic throttle control system includes a warning indicator, wrench warning indicator, on the instrument cluster that illuminates when a concern is present. Concerns are accompanied by diagnostic trouble codes (DTCs) and may also illuminate the malfunction indicator lamp (MIL). (check engine light ) Ford Electronic Throttle Body Failure Diagnosis
Have DTC'S - diagnostic trouble codes checked , follow diagnostic flow chart for said DTC , fix what the problem is , a sensor ,wiring problem , PCM - engine computer etc... then the MIL light will go off on it's own .
Check engine light lit ? or ETC - electronic throttle control .
It should be noted that the ETC system illuminates a powertrain malfunction indicator (wrench) on the instrument cluster when a concern is present. Concerns are accompanied by diagnostic trouble codes (DTCs) and may also illuminate the malfunction indicator lamp (MIL).
Could be a throttle body issue or the APP or the PCM - engine computer .
Your best bet is to take your vehicle to the dealer or some other qualified repair shop .
So you are saying the bulb for the check engine light is burned out and needs to be replaced ?? And the trouble codes you listed are for lean fuel mixture which could point to a vac leak or low fuel pressure.
Diagnostic Test Code (DTC) P0700 is an informational code that is stored in the Engine Control Module (ECM) That informs the diagnostic technician that there are codes present in the Transmission Control Module (TCM) and that the TCM has requested the Malfunction Indicator Lamp (MIL) (AKA - Check Engine Light) to be turned on. This is because the MIL is controlled by the ECM and cannot be turned on directly by the TCM. So, the TCM requests the ECM to turn the light on. To find out the nature of the failure that caused the P0700, one must scan the TCM to retrieve the fault codes stored there. Please note that MOST generic OBD code readers cannot access the TCM - this is the reason for the P0700 code to set in the ECM (to alert somebody with a generic code reader that further diagnosis is needed for the TCM).
Factory service information has a diagnostic procedure for thing's to check . Hooking up a factory scan tool (tech2) would be the first step ,Checking for DTC'S - diagnostic trouble code's
DTC P1661 Malfunction Indicator Lamp (MIL) Control Circuit
A voltage is supplied directly to the malfunction indicator lamp (MIL). The powertrain control module (PCM) controls the lamp by grounding the control circuit via an internal switch called a driver. The primary function of the driver is to supply the ground for the component being controlled. Each driver has a fault line which is monitored by the PCM. When the PCM is commanding a component ON, the voltage of the control circuit should be near 0 volts. When the PCM is commanding the control circuit to a component OFF, the voltage potential of the circuit should be near battery voltage. If the fault detection circuit senses a voltage other than what is expected, the fault line status will change causing the DTC to set.
Perform the Powertrain On-Board Diagnostic System Check first, when the following conditions are present:
• When the MIL does not turn ON when the the ignition switch is turned to the RUN position
Malfunction Indicator Lamp (MIL) Inoperative
There should be a steady MIL with the ignition ON and the engine not running. Ignition feed voltage is supplied directly to the MIL bulb. The Powertrain Control Module (PCM) turns the MIL ON by grounding the MIL control circuit. No MIL with the key ON, engine not running and DTC P1641 set suggests an open in the MIL control circuit.
The diagnostic procedure for this is 17 step's . , the basic thing's checking B+ voltage at the connector for the IPC , checking the control circuit at the PCM connector , using the scan tool to check for bidirectional control of the MIL lamp . Checking wiring circuit for the control circuit . Disconnect the PCM connector that has control side wire for the MIL an ground it an see if the light lights . If it does ,replace the PCM . Check for open wire . ETC........
Check the MIL control circuit for an open.
If the MIL control circuit is open, repair as necessary. Refer to Wiring Repairs .
Finding wire diagrams would be a big help to you .
you can go to your local auto parts store and have them check your obd2 (onboard diagnostics system) to retrieve any stored codes for free. If you reply with those trouble codes I can define them for you and give you a better idea of what it will take to fix them. They can also erase the codes but if there is a problem present than the mil (malfunction indicator light) or engine light will come back on again soon after
Call your local dealer with your vin # ,, there is a recall for that specific code. 96-5-16
